In reinforced concrete constructions, reinforcing bar generates more CO₂ per unit weight than other construction materials. In particular, cutting and bending rebar is the main source of rebar waste in the construction industry. Rebar-cutting waste is inevitable during the construction of a reinforced concrete structure since the rebar is not manufactured as designed. Large amounts of waste can be avoided by utilizing optimal cutting patterns and schedules. This research provides a fundamental analysis of the automatic calculation of column rebar length using BIM-based shape codes to minimize cutting waste to near zero. By employing this approach in practice, it is possible to minimize the rate of rebar-cutting waste, reduce costs, shorten construction duration, and reduce CO₂ emissions. In addition, the development of this research will serve as a clue for the development of BIM-based rebar layout automation algorithms.

The goal of this paper is to analyze the Freedom Center Apacle in Seoul designed by Kin Soo Geun who was a leading architect in Korean Modern architecture. Freedom Center was built in 1963, that was the largest monumental building to support military regime during cold war period in Korea. This paper deals with historical background of construction of Freedom Center and its characteristics compared to similar monumental buildings, especially Corbusier's Chandigar and Kenzo Tange's Hiroshima Peace Center. The Monumentality in Freedom Center came from the reference to these two buildings and its site plan. This paper tried to show how similar the layout of buildings between the Freedom Center and Peace Center. The origin of the sublime aura in Tange's linear layout of Peace Center is from Japanese Famous Shrine(Jinku). Kim translated it to serve the ideological purpose to protect from socialist regime in the name of freedom. Its over-scaled roof and weak contents showed Freedom center was a kind of theaterical setting belong to formalist building. But in spite of its symbolic and representational gesture its also had a architectonic physical quality to make it a monument. The change and duration in time testified the autonomous power of architecture in Freedom Center. Freedom Center was also important for using the exposed concrete and its superior finish. It was influenced not from western way of Benton Brut which was usually called New Brutalism but Japanese way of treating expose concrete. In spite of its limits Freedom center achieved new trend and sensibility in Korean Modern Architecture.

BIPV system not only produces electricity at building, but also acts as a material for building envelope. Thus, it can increase the economical efficiency of PV system by saving the cost for building materials. Bifacial solar cell can convert solar energy to electrical energy from both sides of the cell. In addition, it is designed as 3 busbar layout which is the same with ordinary mono-facial solar cells. Therefore, many of the module manufacturers can easily use the bifacial solar cells without changing their manufacturing equipments. Moreover, bifacial PV system has much potential in building application by utilizing glass-to-glass structure of PV module. However, the electrical generation of the bifacial PV module depends on the characteristics of the building surface which faces the module, as well as outdoor environment. Therefore, in order to apply the bifacial PV module to building envelope as BIPV system, its power generation characteristics are carefully evaluated. For this purpose this study focused on the electrical performance of the bifacial BIPV system through the comparative outdoor experiments. As a result, the power generation performance of the bifacial BIPV system was improved by up to 21% compared to that of the monofacial BIPV system. Therefore, it is claimed that the bifacial BIPV system can replace the conventional BIPV system to improve the PV power generation in buildings.
